BAG-HOLDING DEVICE FOR SCALES.

Application filed October 3, 1913.

Specification of Letters Patent.

Patented Dec. 16, 1913.

Serial No. 793,190.

To aZZ whom, it may concern:

Be it known that I, ERNEST S. KNEELAND, a citizen of the United States, residing at Malden, in the county of Middlesex and State of lvlassachusetts, have invented a new and useful Bagllolding Device for Scales, of which the following is a specification.

The device forming the subject matter of this application is a bag holding attachment for weighing scales, and one object of the invention is to provide novel means whereby the upper end of the bag may be clamped upon the chute portion of the attachment.

Another object of the invention is to provide a device of the type above mentioned, in which the bag may be readily released to permit the same to drop upon a truck or the like.

Another object of the invention is to provide novel means for adjusting the cotiperation between the fixed and relatively movable elements which grip the bag.

lVith the above and other objects in view which will'appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing: Figure 1 shows the invention in side elevation; Fig. 2 is a cross section on the line 22 of Fig. 1; Fig. 3 is a top plan.

In carrying out the invention there is provided a chute denoted generally by the numeral 1 and preferably of frusto-conical form, the smaller end of the chute 1 being downwardly disposed. The chute 1 is provided at its lower end with an inwardly projecting flange 2 defining an opening 3 at the bottom of the chute. A ring at is secured to the lower face of the flange 2 and is provided at its outer edge with an upstanding flange 5 which is spaced from the outer face of the chute 1 to define an upwardly opening groove 6 at the lower end of the chute 1.

Curved supports 7 are secured to opposed portions of the chute 1, the supports 7 terminating in converging, upwardly extending arms 8, the ends of the respective arms 8 being connected by pins 9 or the like, to the supporting links 10. There may be any number of the links 10, the upper ends of the links 10 being pivotally received upon trunnions 11 formed on a scale beam 12.

The invention includes an upright fin 141 which may be secured to the chute 1 in any desired manner. The fin 1 1 is in the present instance shown as provided at its upper end with a foot 15, there being securing elements 16 passing through the foot 15 and through one of the supports 7, into engagement with the chute 1. At its lower end, the fin 1 1 is provided with a foot 17 which may be connected directly with the chute 1. In the edge of the fin 11 there is a notch 18 and below the notch 18, the fin 1% is pro vided in its edge with a notch 19.

Projecting horizontally from the chute 1 is an arm 20, upon which is fulcrumed, as indicated at 29, a loop-shaped lever 21 which incloses the chute 1 as will be understood best from Fig. 3. Secured to or formed integrally with the free end of the loopshaped lever 21 and constituting a part thereof is a handle 22.

iivotally supported as indicated at 23 upon the lever proper 21 is a spring controlled latch 24 which bears against the outer edge of the fin 1 1 and is adapted to engage in either of the notches 18 or 19. Supports 25 extend downwardly from the side portions of the lever 21 and carry at their lower ends curved jaws 26 which are adapted to register in the groove 6.

The bag which is to be supported is de noted by the numeral 27, and, in practical operation, the upper end of the bag is engaged as shown at 28 in the groove 6.

Presupposing that the lever 2122 is in the dotted line position shown in Fig. 2, the latch 21 on the lever is disengaged from the notch 18 in the fin 1 1 and then the free end of the lever is swung downwardly until the jaws 26 fit within the groove 6 and bind upon the upper end of the bag, as will be understood readily from Fig. 2. When the bag is thus gripped, the latch 241- is engaged in the lower notch 19 of the fin 14. The bag will thus be secured to the lower end of the chute 1, whereupon the bag may be filled. After the bag and its contents have been weighed, the latch 24 is disengaged from the notch 19 and the lever 21 22 is swung upwardly into the dotted line position of Fig. 2, the latch engaging in the upper notch 18 in the tin 14.

By this operation, the bag 27 is set free, and the same will drop upon a truck or the like disposed beneath the bag.

The device herein disclosed, although of simple construction and of few parts, is well adapted for the ends in view. 7

Having thus described the invention, what is claimed is 1. In a bag holding attachment, a chute having a flange disposed approximately at right angles to the axis of the chute; supporting means carried by the chute; a lever fulcrumed on the chute and movable substantially parallel to the axis of the chute; means carried by the lever for cooperating in gripping relation with the flange; and latch mechanism connecting the lever with the chute.

2. In a bag holding attachment, a chute provided at its lower end with an upwardly opening groove; supporting means carried by the chute; a lever fulcrumed on the chute and movable substantially parallel to the axis of the chute; means carried by the lever for engaging within the groove; and latch mechanism connecting the lever with the chute.

3. In a bag holding attachment, a chute;

a loop-shaped lever ttulcrumed upon the chute and inclosing the chute; a jaw carried by the lever and cooperating with the bottom portion of the chute; a fin carried by the chute and operating within the contour of the lever; and a yieldable latch carried by the lever and cooperating with the fin.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

ERNEST S. KNEELAND.
